JOHN STURROCK, OF CHICAGO, ILLINOIS, ASSIGNOR T0 INTERNATIONAL HARVESTERCOMPANY OF NEW JERSEY, A CORPORATION OF NEW J ERSIEYL:

JOURNAL-BEARING.

Specification of Letters Patent.

Patented Mar. 13, 1917.

1 Application filed February 2, 1914. Serial N 0. 816,012.

To all whom it may concern:

Be it known that I, JOHN 'STUnRooK, a subject of the King of GreatBritain, residing at Chicago, in the county of Cook and State ofIllinois have invented certain new and useful Improvements in Journal-Bearings, of which the following is a full,

clear and exact specification.

My invention relates to journal bearings in general, and is designed inparticular for use in connection with rotatable disks, being adapted touse either in connection with single disks or furrow openers for graindrills, wherein two rotatable disks are mounted upon a supporting memberin a manner to rotate in substantially vertical planes at an angle withthe line of draft of the machine; the disks converging forward when twodisks are used with their front edges in close contact with each other.

The object of my invention is to improve the construction of suchdevices, faclhtate the assemblage of the various parts in properoperative position, and readjust the.

same in an improved manner to compensate for wear under usage. I attainthese obects by means of mechanism, two embod1-' ments of which areillustrated by the accom-' panying drawings, in which I Figure 1 is atop plan view, partly in section, of a double disk supporting memberhaving my improved journal bearing embodied in its construction;

Fig. 2 is a vertical side elevation of part of the disk supportingmember;

Fig. 3 is a bottom view of Fig. 2;

Fig. 4 is a plan view of one of the hearing blocks;

Fig. 5 is a side elevation of the blocks shown in Fig. 4.

Fig. 6 is a plan view of the other coacting bearing block;

Fig. 7 is a side elevation of the block shown in Fig. 6;

Fig. 8 is a cross sectionof the mechanism designed for use in connectionwith a single disk furrow; and

Fig. 9 is a side elevation of the mechanism shown in Fig. 8.

Referring to the drawings, 1 represents a disk supporting memberprovided with forwardly converging bearing faces 2 upon opposite sidesof its lower end and laterally extending boss members 3 having an axialopening 4 extending therethrough and peripherally disposed notches 5,the bosses being surrounded by a series of concentric radiallycorrugated cam faces 6 of ratchet form. 7 represents a cylindricalbearing block having peripheral bearing surfaces 7 and provided upon oneside with radially corrugated concentric cam faces 8 corresponding tothe cam faces 6. As shown in section in Fig. 1, each of these blocks isprovided with an axial opening that receives the boss member 3, and theopposite side of the block (Fig. 5') is provided with a laterallyextending concentric rim 9 having a series of radially disposedlubricant conducting channels 10 therein. 11 represents a complementalbearing block of substantially the same diameter as the blocks 7 andprovided with a laterally disposed concentric rim 12 and an axial boltreceiving opening 13. Extending laterally from the inner side of the rim12 is a boss or positioning member 1 1 having a laterally extending lipmember 15 at one side thereof that, in the assemblage of the parts, isreceived by the peripheral notch 5 in the boss member 3 in a manner tolockthe members against independent r0- tation.

16 represents a'furrow opening disk and 17 a cup-shaped casing having aflange member 18 whereby it is secured to the disk. This casing 17 isprovided with a bearing surface '19 journaled upon the bearing surface 7on the member 7, and an inwardly extending annular flange member 20journaled upon the rim 9, and a laterally extending rim member 21 thatreceives the bearing block 11, likewise provided with a bearing surface19. 22 represents a dust excluding felt washer interposed between thedisk and the adjacent face of the supporting member 1, the inner end ofthe block 7 preferably being reduced in diameter and having the samefitting snugly thereover. The bearing block members 11 and the coactingdisks are secured to the member 1 in operative relationby means of abolt 23, and adjusting washers 24 may be placed between the blockmembers 7 and 11 to regulate the space required by the annular flangemember 20 for a free rotation of the disk.

The single disk form of the construction shown in F igs. 8 and 9 isobviously of'substantially the same construction as that hereinabovedescribed and will operate in substantially the same y, the principaldifference being that the ositioning member and support are in i ertedrelation.

In assembling of the various parts of the mechanism it is important in adouble disk mechanism that the front converging sides of the disks bebrought in close contact with each other, and in a single disk mechanismthat the disk rotates in close proximity with the grain boot andscraper. I-Ieretofore it has been necessary to have the parts ofaccurate dimensions and closeness, smooth and reguiar in form, theresult being that a large number of pieces were rejected under the mostrigid inspection. lVith my inven: tion the disks are adjustable bodilyby means of the opposing cam surfaces on the bearing block, the bearingblock being adj ustable angularly in either direction, whereby the disksmay be adjusted toward or from each other when two are used, and may beadjusted toward or from the boot where a single disk is used, thecorrugations upon the opposing cam surfaces effectually retaining theparts in adjusted relation.

lVhile I have specifically described but one form which my invention mayassume in practice, it is, of course, to be understood that the formshown for purposes of illustration may be modified without departingfrom the spirit of my invention.
